clusterhap: Clustering Genotypes in Haplotypes

One haplotype is a combination of SNP
(Single Nucleotide Polymorphisms) within the QTL (Quantitative Trait Loci).
clusterhap groups together all individuals of a population with the same haplotype.
Each group contains individual with the same allele in each SNP,
whether or not missing data. Thus, clusterhap groups individuals,
that to be imputed, have a non-zero probability of having the same alleles
in the entire sequence of SNP's. Moreover, clusterhap calculates such
probability from relative frequencies.
